Abstract :

Knowing the association of family history of heå loss and consanguinity with congenital heå loss provides important clues to prevent the occurrence in subsequent generations. A case control study was designed on 30 children with permanent heå loss and 30 children with normal heå from Feb.2014 to Dec.2015.The case control ratio was 1:1. Detailed history was taken from the parents regarding family history and consanguinity. 36.7% of cases had a positive family history. 56.7% of cases had parents with consanguinity. Family history and consanguinity seem to be important risk factors of congenital heå impairment, both in isolation and in combination.
